Here's a suggestion on the thumbnail... In Pro Pak, at least, since you create a CR2 that you will probably later remove, you can use the png file the CR2 generated for your new PZ2 (rename if you renamed the PZ2). You'll probably want to do a rendered version for your thumbnail if you are redistributing. The utility works very nicely. Rob wrote up some nice, even if quick and dirty, instructions. Thanks, Rob.
